To all whom. it may concern Be it known that 1, James F. Mirr'riinws, a citizen of the United States, residing at Pottersville, in the county oi Bristol and State of ltlassachusetts, have invented an Inn provemcnt. in Knot-Tying implements, of which the following description, in connection with the accompanying drawings, is a specification, like letters on the drawings representing like parts.

lhis invention relates to knot tying im plements particularly intended for use in piecing up the broken ends of spooling machines. it. however, is capable of use in other relations and for other purposes.

In order that the principles of the invention may readily be understood, 1 have disclosed a single embodiment thereof in the accompanying drawing, wherein- Figure 1 is a side elevation of a knot tying implement embodying my invention; Fig. 2 is a front end ele'ation thereof; Fig. 3 is a plan view of the implement and showing the first position of the threads thereon; and Figs. 4, 5, 6 and 7 are enlarged views of a portion of the implement illustrating the several steps of the knot forming operation.

While the knot tying implement of my invention may be of general application, it is particularly intended for use in piecing up broken ends in a spooler. When an end is broken, the operative usually places the left hand upon the spool to stop its rotation upon its spindle and with the other hand grasps the broken ends extending from the spool and the bobbin in its holder, both hands being used to tie the knot.

.Yhile the implement herein disclosed may be supported upon the hand of the operative in any suitable manner, it is preferably supported upon the left hand; that is to say, upon the hand used to stop the rotation of the spool whose end is broken. Preferably also the implement. is supported upon the torefinge" of the left hand and in such manner that the knot tying operation can he performed wholly by the right hand of the user, as will be more fully described. The knot tied is what is known as the spoolers knot.

Referring more particularly to the drawing. the knot tying implement comprises a preferably metallic piece or strip 1, herein termed a base or thread receiver. Attached thereto in any suitable manner is a ring 2, within which a digit of the user and preferably the forefinger of the left hand may be inserted. I contemplate adapting the ring 2 to fingers of different size. To that end I may either attach the ring to the base, but in such manner as to permit it to be readily disconnected and a. different sized ring substituted, or as shown in Fig. 2 I may form the ring as an open one and of material which may be readily bent so that the ring may be expanded or contracted to the proper size. It the ring be detachable, it may be secured in any suitable manner, as by means of a screw. If permanently attached it may be connected to the base in any suitable manner or formed therewith.

The base or thread receiver 1 is provided with an extension 3 constituting a bight former, herein shown as reversely bent and having side guiding edges 3, 3 and having at its end a knot former t shown as an eye or looper and positioned preferably at a slight distance from and substantially parallel with the base 1 and also preferably transversely thereof, the bight former 3 being shown as twisted as at 5 to bring the knot former i into the transverse position described. In this embodiment of the invention, the bight former is shown as formed with and overhanging the base or receiver 1.

I preferably provide a thread introducing guide and a thread exit guide. The thread introducing guide is here represented as a preferably metallic piece 6 secured to the under face of the base 1 and extending upwardly adjacent the inner edge of such base. The thread exit guide is represented as a notch or slot 7 formed in the base preferably immediately beneath the knot former 4. If desired, the edge leading to the exit guide may be inclined thereto as represented at 8.

I provide any suitable means to sever the threads after the formation of the knot, and to that end may provide any suitable construction of movable blade or may provide the base 1 with a sharpened edge or attach thereto a stationary blade in proper relation to the knot former 4. In the present embodiment of the invention, 1 have,

however. illustrated. a blade 9 adapted tot he ope ated by the. user and preferably by the thumb oi the hand whereon the imple ment is carried. llerein the blade 2) is represented as pivoted at 10 upon. the rear end of the base l and as having a downwardly bent thumb piece ll which may receive the pres sure ol the thumb to force it against the threads. The base is provided with a spring 12 to return the blade to non-severing position.

it in use the implement is mounted upon the left hand of the operati' e, the broken ends may be grasped in the right hand and ii'ltirotilueed through the guide (3 and led across the base 1 in the manner indicated, at l3 in Fig. The threads then lie back of and below the knot i oi'n'ier l. The threads are then by the right hand slid along the remote or outer edge at the base 1. this edge serving to guide the threads in their movement. ln this manner the threads are brought above the eye or looper 4c, the threads (Xt'eimling from above the eve to the outer guiding edge 3 ol the bight former as illustrated in 4. The movement of the right hand carrying the threads is con tinued. the hand being moved in. a curve from a position hack ol. the implement and treat substantially the plane of the base 1 to a point in 'lrr-nt thereoi. This wraps the threads in iarallelism in a common bight about the liiight 'lormer 3, briiigine the free ends of the threads guided by the edges 3, 3, down into the knot liormer l in the mannrr illustrated in Fig, Further pull upon the threads d aws them off the tongue ll, so that the threads are held by the hook 15 of the knot former l. as illustrated in Fig. 6.

the knot lvingg between the thread introducing; guide (3 and the knot former 4t. ll hen the. threads are in this position the ends are severed by movement. of the blade 9. The

bl; in. do not in this embodiment: of the invention make a shear cut. but the threads are, in the d jCl'llJQCl operation, drawn stiflicientlv taut severance by the blade. A fter the thread ends have been st-n'ered the severed ends cling slightly to the hook 15. as represented in Fig. 7, so that in practice the 'PQlnl'lYt may take hold of one oi? the thread ends now joined and remove her left hand from the spool. By taking hold of one of "he thread ends at this point in the o fieration a kink is prevented. That is to say. the threads are prevented from twisting together above the knot as is now done in certain types of knot tying device. Moreover the operative can at a glance inspect the knot while the thread end is held by the rand. This can be done without. appreciable loss of time. By drawing upon the oined threads the knot falls off the hook 15 and the operation is completed.

From the foregoing description, it will be apparent: that the knot tying implement of my invention is one which permits the very rapid tying oi. the knot and also permits inspection of the knot before it is rel ased and avoids all kinking or twisting together at the threads. As the implement can be carried upon a linger ol that hand which is usually placed upon. the spool to stop its rotation when an end bl'QllkS down. the operative has one, hand wholly free for manipulating the thread and can if desired readily sever the thread by the thumb or another linger oi the hand whereon the implement is mounted. l urthermore the implement is exceedingly simple and inexpensive and does not have parts liable to get out at order or to became broken.

Having thus described one illustrative embodiment of my invention, I desire it to be understood that although specific terms are employed, they are used in a generic and descriptive sense and not for purposes of limitation, the scope of the invention being set forth in. the following claims.
